PNA-1M 8D2.960.000

8D2.960.000 for aviation fuel transfer

The decimal number 8D2.960.000 identifies the PNA-1M pumping unit in technical documentation. In aviation service, such an item is used not as a permanent onboard aircraft unit, but as portable ground-support or service equipment. It helps refuel aircraft or special equipment from temporary fuel storage when normal refueling infrastructure is limited. This can be relevant for remote airfields, field bases, expedition work, temporary operating sites and maintenance situations where fuel must be transferred safely and with filtration before entering the tank.

Fuel delivery function of the PNA-1M

The PNA-1M provides fuel transfer with a high nominal flow rate for a portable unit. It can draw fuel from a source container and deliver it to the receiving tank through a hose set. The unit is designed with defined suction and discharge height limits, so hose routing and placement of the source container matter in real use. If the suction height is exceeded or the inlet line is poorly arranged, the pump may lose efficiency, pull air into the fuel line, or fail to maintain the required flow rate.

PNA-1M filtration system

A major advantage of the PNA-1M is that it does not simply move fuel from one container to another. The unit includes filtration for mechanical contamination. Fuel passes through filter elements that provide coarse and fine cleaning, with nominal filtration down to 10 microns. This matters in aviation refueling, because contamination from drums, field tanks or temporary storage can create problems in aircraft fuel systems. The filter elements are replaceable and non-regenerable, so their condition and replacement schedule should be monitored during operation.

Fuel compatibility of the PNA-1M unit

The PNA-1M is suitable for aviation kerosene grades such as TS-1, T-1 and T-2, as well as aviation gasoline grades including B-70, B-91/115, B-95/130 and B-100/130. It may also be used with regular gasoline where permitted by the operating documentation. Fuel compatibility should always be checked before use, especially when the unit has previously been used with another fuel grade. Cleanliness, absence of water, hose condition and filter condition are important, because a portable unit is often used in less controlled field environments.

Electrical power supply for PNA-1M operation

The PNA-1M operates from a 27 V DC power supply. In practice, this may be an aircraft onboard DC network, a ground power unit, a vehicle power system or a dedicated DC power source, provided it meets the required voltage range and connection rules. This makes the unit convenient for field use because it does not require an industrial AC supply. At the same time, the electrical cable, polarity, connector condition and power source capacity must be checked before operation. Poor electrical supply can reduce pump performance or cause unstable operation.

Operation time and handling of the PNA-1M set

The PNA-1M is intended for portable use, but it still has operating limits. Continuous operation is limited to three hours, which is enough to transfer a significant amount of fuel if the unit is working within its rated parameters. The pump assembly and hose set are handled as separate parts of the complete kit. The pump itself is compact enough for field use, while the hoses are normally transported separately in a case. Before use, the operator should check the pump, hose connections, filters, seals, grounding procedure and the cleanliness of both the fuel source and receiving tank.
